South side Perito Moreno glacier

I hope that one day Manu, you can do this trip ! My few photos are unable to show the enormous beauty of this place.

By chance Julicarm, this is not a product of the warming of the earth. This glacier is one of the few who does returns not. On the contrary, he moves forward and touches the peninsula of Magallanes by blocking the passage of water from the lake. The water below eroding the wall, to form a cave and it collapses. This process of blocking and the collapse takes at least two years.

It is precisely the erosion by water below the surface that brought down the ice dam. Good observation Jofu !
